PS4 Slim CD Drive stop working overnight

Hi, my PS4 slim suddenly stop working after 10+ hour of non stop playing at night and on the morning when trying to dismount the CD it wouldn't. i used manual eject button to retrieve the CD and from that day on the CD drive seems doesn't get any power the consol works fine and the power will come on when i try to insert the disk but it will not accept the disk nor did it start to spin or read when i use the manual eject in reverse to insert the disk. i watched all videos on how to repair from youtube and i tried everything from dismantling the whole PS4 and didn't find anything wrong with it, the disk drive rollers are ok, everything is in place the dynamo works with other batteries and power reach the mother board since i check and get the 5v in the power supply i inspect the casble which feed power to the disk drive everything is ok even i tested every fuse in the power supply unit and on the mother board and everything is ok but still my PS4 slim cant accept disk or play them. i came to conclude that the power for the disk isn't been delivered but i did everything in my power and would appreciate any suggestion or help since i don't have another PS4 which i can test the CD drive on and i am very desperate it's only been a year since i purchase the PS4 from the Nederland and i leave in Ethiopia and couldn't find any repair shop here and the only viable option for me is to fix it myself. hope to hear from you soon. Thank you in advance for your cooperation.
